A BMW insider said that the Mini’s lineup by 2020 will include a five-door station wagon, a van and maybe even a notchback sedan, according to a report from Automobilwoche, Automotive News' German sibling publication. This station wagon will be based on a new BMW Group front-wheel-drive platform that will be launched in 2014 on the second-generation Mini Cooper hardtop.

The van is built on the same platform as the Mini Countryman. However, the source said that no final decision has been made on the notchback sedan, which is being considered for the market in China.

The source said that the Mini sedan is being “hotly debated”, according to Autonews. At the Detroit Auto Show last month, Kay Segler, Mini's global brand boss, said during the Detroit auto show that there will be three models that will join the lineup by the end of the decade but he didn’t name the models.

Presently, Mini offers five models but a sixth one – the Roadster – will set foot this month in U.S. dealerships. And in the first quarter of 2013, a coupe version of the four-door Countryman crossover, named the Countryman Coupe, will be launched. This model had made its debut at the 2011 Detroit auto show as the Paceman concept.
